              Ethernet over SDH network termination equipment provides simple and   cost-effective solution for bridging Fast and Gigabit Ethernet traffic   over STM-1 or STM-4 circuits. They are widely used for backhauling   mobile base stations and IP DSLAMs, providing from N*2Mbps to wire-speed   Ethernet connections.
